Officials in the United Kingdom have issued a warning regarding the potential risks associated with popular weight-loss medications like Ozempic for individuals undergoing surgery. These medications, which include semaglutide (Ozempic and Wegovy) and tirzeparide (Zepbound and Mounjaro), work by slowing the release of food and liquid from the stomach, leading to increased feelings of fullness and aiding in weight loss. However, this mechanism can also raise the risk of a rare surgical complication known as aspiration, where stomach contents enter the lungs.
Patients typically fast before surgery to minimize the risk of inhaling stomach contents while under anesthesia. However, individuals taking certain weight-loss and diabetes medications may still have residual contents in their stomach even after fasting. The Medicines and Healthcare products Regulatory Agency (MHRA) in the UK has reported cases of patients on these medications experiencing aspiration during surgery, with some developing aspiration pneumonia as a result.
It is crucial for patients to inform their healthcare providers about their medication use before undergoing surgery. While it is not recommended to stop or change medications without medical advice, healthcare professionals should assess the additional risk posed by drugs like Ozempic and Zepbound, especially for patients with underlying conditions that may further delay gastric emptying.
Similar warnings have been issued by medical authorities in Europe and the United States, as the popularity of weight-loss medications continues to grow. The European Medicines Agency has released guidelines for managing surgical patients on drugs like Wegovy, Mounjaro, and Tirzepatide, citing a potential but biologically plausible risk of aspiration.
While some organizations, like the American Society of Anesthesiologists, have recommended discontinuing medications like Ozempic before surgery, the FDA has taken a more cautious approach. The FDA updated labeling on drugs like Ozempic to include information about rare cases of aspiration, emphasizing the importance of communication between patients and healthcare providers.
Ultimately, individual risk assessments and tailored risk-reduction strategies are recommended for patients using weight-loss medications like Ozempic before surgery. It is essential for patients to be proactive in discussing their medication use with their healthcare team to ensure safe and successful surgical outcomes.
